Sigh ye are all uneducated about computers... First macs are the worst things ever made! I would kill myself before I had to use mac as my main operationg system. Now I really like their hardware which is another story. And that is why I have a iMac sitting next to me with vista booted on it.
Now bink I suggest you try reinstalling vista one more time. I have been using vista since beta 1 even before it was called vista and just longhorn. And have been using it as my main os since beta 2. I tried using my xp boot the other day... man once the loading screen started I had enough time to go make myself some lunch, eat it slowly, and watch the tube. I come back and it just finished booting. great now to login. Another 20 mins down the drain. Now vista boot. *presses power button* 5 minutes later i am in firefox doing my normal checkups on the server. I couldn't live without vista it is ten times better than xp no matter what others say. And to all those who are waiting cause of bugs, there are no bug except the copy, cut, delete bug. I have been using this since beta 1! bugs is just a media hype!
so go by the upgrade to vista now!
